This one is a drilling. The lockup is pretty darn solid. Buttstock replaced more recently. All small parts work as they should.
Damascus barrels made by A. Linder for the USA importer Charles Daly. In 10x10x45-70, this is BP only. Circa late 1880s or thereabouts.
But the bores are shiny and the rifle barrel has some very minor pitting, the rifling is deep with no throat/chamber erosion. If I was a betting man, I would say the rifle was shot more than the pair of shotgun barrels. But that's just my impression.
I intend to hunt this one friend.
